Textbook Used by Orville Wright, "Intermediate Arithmetic," 1876

Milton and Susan Wright encouraged an interest in learning in their children Reuchlin, Lorin, Wilbur, Orville, and Katharine -- though not necessarily in formal education. Katharine was the only Wright child to finish college, graduating from Oberlin in 1898. Neither Wilbur nor Orville finished high school, but they learned much from their father's extensive home library.
